Software Situation

Common circumstance of diaphragm coupling used to variable frequency pace control products

JMB sort coupling is applied to Daqing Oilfield Thermal Electricity Plant

In accordance to the requirements of Daqing Electrical Power Company, Daqing Oilfield Thermal Power Plant must dynamically modify the electricity generation in accordance to the load of the power grid and marketplace demand, and have out the transformation of the frequency converter and the suction supporter. The motor was originally a 1600KW, 730RPM non-frequency variable velocity motor matched by Shenyang Motor Manufacturing facility. The speed handle method following altering the frequency is handbook control. Press the button speed to boost 10RPM or fall 10RPM. The coupling is nevertheless the first elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is often destroyed, which directly impacts the typical energy generation.

It is found via analysis that in the procedure of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the supporter impeller is 3.three meters) and is reduce off, which has wonderful damage to the motor and the enthusiast.

Later, they switched to the JMB460 double-diaphragm wheel-sort coupling of our manufacturing unit (patent amount: ZL.99246247.nine). After one hour of harmful experiment and a lot more than one particular yr of operation test, the gear is operating very properly, and there is no Change the diaphragm. twelve models have been rebuilt and the operation is in good problem.
